The original star of the Alien film franchise says she's hopeful about reprising her role as tough-as-nails survivor Ellen Ripley in another sequel.

Weaver told the Comic-Con crowd during a Saturday panel celebrating the 30th anniversary of the sci-fi sequel Aliens that District 9 filmmaker Neill Blomkamp pitched her an idea for another installment when they were working together on his 2015 film Chappie.

"Four months later, I got a script that was so amazing and gives the fans everything they are looking for - plus innovates in a lot of ways," Weaver said.

"(Blomkamp) has work to do, and I have work to do," Weaver said. "I am hoping when we finish those jobs, we will circle back and start to do it."

The 'Alien' movies: Where are they now?
Weaver last portrayed Ripley on screen in the 1997 sequel Alien Resurrection, the fourth film in the series that ended with a clone of Ripley arriving on Earth. (The original Ripley sacrificed herself at the conclusion of 1992's Aliens 3.)

Weaver told 6,500 fans at San Diego Comic-International that she wasn't interested in an Earth-set sequel because she thought "Earth was boring".
